Hi Realigned,
The better options and possibilities I’m aware of in and around the Phoenix area (subject to the quality/value guidelines here) are listed in post #4 here.
You are very fortunate to live in the Phoenix area since several of the manufacturing members of this site are based there which gives you the chance to test mattresses in person that most of the rest of the members that live in other areas of the country can only order online without being able to test them first.
I would certainly include zoned mattresses in your research but I wouldn’t limit your research to zoned mattresses alone. Your own careful testing will tell you whether a mattress is a good match for you whether it is zoned or not.
Latex is a great material and in general it’s the most durable of all the foam types but the choice of material is always a preference choice not so much a “better/worse” choice. Different people can have a very wide range of preferences about the types of materials and mattresses they like best and for some people it’s their favorite material and some people don’t like it at all. I would definitely include it in your research so you can decide how it feels to you and you have some great latex and latex hybrid options available to you in the Phoenix area.
